Thumbs up just for being linux and cheating ELF into 256B... and music is quite an achievement.

The rest is ... well... done in real hurry I suppose, nothing impressive (for example the 24bpp pixel storing can be also `stosd` `dec edi` to have only +1B when compared to 32bpp version).

I'm highly interested into trying my own 256 in linux, so I hope your addition of source means "for any other demo scener who needs linux 256 skeleton). (next time add some license info in source please)

Unfortunately I have KDE Neon (based on ubuntu), so I don't have /dev/dsp device, but I will try later to run this either without it with patched source, or some workaround, just wanted to say big thank you for the stuff I already found here...
